A former Spring Branch middle school teacher, previously accused of having sex with one of her students, faces new charges after she was found with the same teen at her home.

Kathryn Camille Murray, 29, was fired from Memorial Middle School, where she taught for three years, after allegations arose last February that she had sex with an eighth-grader several times in his home, at a hotel and in her classroom. Murray was charged last year with three counts of sexual abuse and one count of improper relationship with a child, court records show.

This weekend, the Houston woman was charged with harboring a runaway child. She was arrested at 3 a.m. Friday at her house after she was found with the same 15-year-old, who had run away from his parents house.

Court records show that last year the student's 12-year-old brother caught his brother in bed with the woman he called, "Mrs. Murray." The 12-year-old saw his brother on the bed and a figure under the bedding, according to the arrest affidavit.

The 15-year-year allegedly said to the person under the covers, "Mrs. Murray, say hi to (my brother)" to which the person under the sheets said, "Hola." A faculty member reported the incident to the school's principal and she was removed from campus that day, district officials said.
